SY20518
Overview
The SY20518 is a 2.6V to 5.5V input voltage range, high efficiency, fixed frequency Buck-Boost converter that can provide up to 2A of continuous current to a load that requires a voltage below equal or above the input voltage. The converter can provide power for system powered by either a two-cell or three-cell alkaline, Ni-Cd or Ni-MH batteries, or a single cell Li-Ion or Li-polymer battery.
